Description
Technical field
The utility model relates to reboiler technical field, particularly relates to a kind of propane propylene knockout tower reboiler.
Background technology
Propylene is important Organic Chemicals, except for the production of except polypropylene, still produce acrylonitrile, the primary raw material of the products such as butanols, octanol, expoxy propane, isopropyl alcohol, propyl benzene, acrylic acid, carbon back alcohol and nonyl phenol, the oligomer of propylene is the main component improving octane number.Trends In Preparation of Propene By Catalytic Dehydrogenation of Propane can produce more propylene than hydrocarbon steam cracking, and when producing propylene with steam cracking, propene yield only has 33% at most; And produce propylene with catalytic dehydrogenation methods, total recovery can reach 74%-86%, produces unique Product with unique raw material, low than hydrocarbon steam cracking of the equipment investment of catalytic dehydrogenation, and adopt the method for catalytic dehydrogenation, liquefied petroleum gas resource can be effectively utilized and make it to change useful alkene into.Do not applied due to existing source since the nineties in 20th century and need, dehydrogenating propane has become the propylene source of the 3rd.
Need propane to be separated with generated propylene after dehydrogenating propane, wherein distillation operation is the maximum unit operations that consumes energy in piece-rate system.As far back as nineteen eighty-two, the distillation process power consumption of the U.S. just accounts for 41.2% of petro chemical industry, accounts for 8.24% of whole industry, accounts for 2.99% of national total energy consumption.Any slight improvements of distillation process efficiency, all can produce huge economic benefit.
Propane propylene distillation system produces an operating unit very important in the whole technological process of propylene, directly affects purity and the yield of final products propylene.What commonly use in propane propylene distillation system is heat pump flowsheet, and the features heavily boiled at the bottom of heat pump flowsheet rectifying column has a narrow range of temperature, generally at about 6 DEG C.
Also there is following problem in the design of existing propane propylene knockout tower reboiler:
Existing reboiler structure, fluid distrbution is uneven, easily causes heat exchange efficiency to decline; Easy generation vibration; Pressure drop causes greatly setting height(from bottom) to increase, and adapter makes greatly stringing difficulty increase.
Utility model content
The purpose of this utility model is to propose a kind of propane propylene knockout tower reboiler, can improve the uniformity of housing inner fluid, reduces heat exchange dead band, can reduce vibration.
For reaching this object, the utility model by the following technical solutions:
A kind of propane propylene knockout tower reboiler, comprise housing, described housing is provided with four fluid inlet adapters and four fluid issuing adapters, described enclosure interior is provided with distributor pipe, the axis of described distributor pipe and the axis being parallel of described housing, described distributor pipe is taken over described four fluid inlets and is communicated with, the sidewall of described distributor pipe is provided with multiple hole, described hole is taken over towards described fluid issuing, fluid is taken over by described four fluid inlets and is entered described distributor pipe, described distributor pipe is flowed out from described hole, then described fluid continues to flow to described four fluid issuings adapter.
Further technical scheme, the circulation area of described distributor pipe is greater than the circulation area of described fluid inlet adapter.
Further technical scheme, the circulation area of described distributor pipe is 2-5 times of the circulation area of described fluid inlet adapter.
Further technical scheme, is provided with support plate in described housing, and described support plate is perpendicular to the axis of described housing.
Further technical scheme, described hole and the interlaced setting of described support plate.
The beneficial effects of the utility model:
The propane propylene knockout tower reboiler that the utility model proposes, inside is provided with distributor pipe, the phenomenon that effectively can reduce the fluid distrbution inequality of different piece occurs, and the circulation area of distributor pipe is greater than the circulation area of fluid inlet adapter, entering in housing smoothly of fluid can be ensured, and larger pressure drop can not be produced; Instead of deflection plate with support plate in this reboiler in addition, pressure drop reduces, and decreases the vibration of internal heat exchange tubes, can also make the height reduction that this reboiler is installed on knockout tower in addition, facilitate assembling; The fluid inlet adapter of this reboiler and the quantity of fluid issuing adapter are respectively four, because the quantity of the fluid inlet adapter in the more existing reboiler of its quantity and fluid issuing adapter increases, therefore the internal diameter of corresponding adapter can reduce, and can also facilitate pipe arrangement, and effective stringing area increases.

Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Embodiment 1
As shown in Figure 1, a kind of propane propylene knockout tower reboiler, comprise housing 1, described housing 1 is provided with four fluid inlet adapters 2 and four fluid issuing adapters 3, after adding the quantity of fluid inlet adapter 2 and fluid issuing adapter 3, the internal diameter of phase adapter can reduce, phase adapter wall thickness can correspondingly reduce simultaneously, reduce costs, and can facilitate pipe arrangement, effective stringing area increases, described housing 1 inside is provided with distributor pipe 4, the axis of described distributor pipe 4 and the axis being parallel of described housing 1, described distributor pipe 4 is communicated with described four fluid inlet adapters 2, the sidewall of described distributor pipe 4 is provided with multiple hole 6, as illustrated in fig. 1 and 2, described hole 6 is towards described fluid issuing adapter 3, fluid enters described distributor pipe 4 by described four fluid inlet adapters 2, described distributor pipe 4 is flowed out from described hole 6, then fluid continues to flow to described four fluid issuing adapters 3, the setting of distributor pipe 4, the problem of fluid distrbution inequality in housing 1 is prevented to produce, ensure that heat exchange efficiency can not be affected.
